What happens if you drive with a low radiator temperature?

[Dana]

Driving with a low radiator temperature can result in reduced engine efficiency and increased fuel consumption. Engine efficiency refers to the effectiveness with which an engine utilizes the chemical energy of the propellant. During engine operation, only a portion of the thermal energy contained in the fuel is converted into propulsion work, while the rest is lost as thermal or kinetic energy. The radiator, also known as the cooling system, is a crucial component of a water-cooled engine. Its primary function is to dissipate heat and prevent the engine from overheating. The coolant absorbs heat in the water jacket, flows to the radiator to release the heat, and then returns to the water jacket in a continuous cycle. The radiator mainly consists of the radiator core, water pipes, cooling fins, upper tank, and lower tank.
